Objective: The purpose of this study was to provide an anatomical reference for cortical bone and soft tissue thickness, and the attached gingiva width in the mandible. Methods: Fifteen males and fifteen females participated in this study. An acrylic template was fabricated and the radiopaque markers were bonded on the estimated alveolar crest to take measurements of the hard and soft tissue thickness at the same locations. CT images were taken in samples wearing an acrylic template. Cortical bone and soft tissue thickness were measured at 2, 4, 6 and 8 mm from the alveolar crest in interradicular spaces from central incisor to first permanent molar. The attached gingival width was calibrated. Results: Cortical bone thickness was $1.33{\pm}0.38mm$ and soft tissue thickness was $1.49{\pm}0.54mm$. Cortical bone thickness was increased in the posterior area, while it was not the case for the soft tissue thickness. In addition, the total thickness was $2.82{\pm}0.70$. The attached gingival width was wider in the anterior area compared to that in posterior area. Conclusion: These results suggest that the attached gingiva width should be considered upon placement of mini-implants in the mandibular posterior area for orthodontic anchorage.

This study was conducted to determine factors affecting professionalism of community health practitioners (CHPs). The participants in this study were 153 community health practitioners working in G province with structured self-report questionnaires from 20 August to 25 September 2017. Data were analyzed by descriptive statistics, t-test, ANONA, Scheffe's test, Pearson's correlation coefficients and stepwise multiple regression using the SPSS 20.0 program. There were statistically significant differences according to income (F=6.951, p<.001), work experience (F=5.245, p=0.002) and motivation for choosing a community health practitioner (F=3.676, p=0.004). The highest related factors were job satisfaction (${\beta}=0.320$, p<0.001), individual disposition (${\beta}=0.291$, p<0.001), income (${\beta}=0.283$, p<0.001) and job continuance (${\beta}=0.176$, p=0.009). These variables explained 49.6% of the total variance in professionalism. These findings suggest that it is necessary to develop a convergence program and policy support at the individual and organizational level to strengthen the professionalism of community health practitioners.

Matching spots between two sets of 2-dimensional electrophoresis can make it possible to find out the generation, extinction and change of proteins. Generally protein spots are separated by 2-dimensional electrophoresis. This process makes the position of the same protein spot a little different according to the status of the tissue or the experimental environment. Matching the spots shows that the relation of spots is non-uniform and non-linear transformation. However we can also find that the local relation preserves the topology. This study proposes a matching method motivated by the preservation of the topology. To compare the similarity of the topology, we compared the distance and the angle between neighbour spots. Experimental result shows that the proposed method is effective.

The purpose of this study is to investigate the relationship of grit with well-being and self-efficacy. Grit was considered as a two-factor variable with consistency of interest and perseverance of effort. For the empirical analysis, data were collected from the sample of 237 nurses working at general hospitals. Collected data were analyzed using SPSS 26 to test the hypothetical relationships. It was suggested that two factors of grit would be possible associated with well-being. However, the results of this study showed that the consistency of interest part of grit had non-significant effect on well-being, Perseverance of effort part of grit had indirect effect on well-being through fully mediation effect of self-efficacy. This study confirmed that grit, some how, positively related to well-being and variables such as, self-efficacy, could be a important variable to bridge grit to well-being. Further studies were suggested to perform studies on more about grit's two factors and unexplored external variables between grit and well-being of nursing professionals.
